Mutant Handpan are something kind of new that we've only seen popping up (or at least going by that name) in recent times. And in addition to its twelve notes, this instrument also features a Gudu Hang style udu-port, plus a mandala design on the under-shell.- making it quite the showpiece (you can take a listen below)...

Popularised by the Golden Mutant Handpan of Jan Borren, the Mutant-label appears to refer to the inclusion of a pair of additional “eye-like” notes towards the front of the Handpan. And this specific configuration (that a number of other makers are also now beginning to make use of) appears to have been born when Handpan-musician Kabecao visited Jan Borren at his workshop in the Netherlands - to co-create the instrument that you can hear below...

As a side-note, if our own experience is anything to go by, their probably isn't a Handpan musician alive who hasn't, while out with Handpan on back, been told that they kind of look like a Ninja Turtle. And for those happy to embrace their turtle-power, and become a bona-fide Handpan-wielding Hero-in-a-half-shell, you could do worse than to check out the totally-bodacious Turtle case from Hardcase Technologies (pictured above).
